From the looks of it, your lights are 10-12" above the water and your corals are several inches below the water surface? Am I seeing things correct? If so, you might want to slowly increase your intensity over the course of a couple months. I would suggest about 1-2% a week keeping a close eye on the corals to make sure they don't respond badly. You may also want to reduce your color a bit. Maybe down to 60% over the course of a couple weeks and see what that does. I would wait until you have increased the intensity (Assuming I am correct about the height above the water and distance below the surface) first before changing the color or do the color first followed by the intensity. You just don't want to make too many changes at once because you won't know what caused an issue should your corals respond adversely.

Hi Scott,

Nice to hear from you again .

You are right , my lights is about 11 inch above water surface and corals is about 12 inch below water surface.

You mean I have to gradually increase the intensity for about 8% - 16 % in total? Considering about 1-2 % / weeks for couple of months ? Ok , I will make adjustment first on intensity and then see if corals is ok with that . Furthermore , as I understand what you suggest is intensity first before colors or colors before intensity , can I make adjustment of both gradually at the same time which means increasing intensity 1-2 % per week and decreasing color 1-2% per week at the same time ?

I am suspecting that corals also react to my present high po4 (@ 0.18 ppm) but I also suspect my lights has to do with it too as in the past when I have ULNS thru Biopellet corals already response like this , it just so happened when I switch to KZ and its does not work well for me that causing my po4 unable to lower down Inspite of continuing dosing so now I switch back to BP and trying to reduce my po4 with GFO too. (Anyway , this us another topic).

Cheers,

Good to hear from you too!

You could change both intensity or color but I would change one or the other and not both at once. That way you can monitor your corals and see how they react and not have to guess what the issues is should they respond bad. I don't think the color is your issue. At least not with the intensity at 80%. While the current color % is probably not helping, it's probably not hurting either. I don't think your intensity is high enough though given the distance the lights are from the surface of the water and how deep the corals are from the surface.

Raise the intensity slowly (Max 1-2% per week). I think 2% is perfectly fine. Raise it to 90% over the course of 5 weeks and see how the corals are doing. If you see the corals respond bad, then back off 4%. That's the idea of taking it slow. If you see a bad response, you take it back a couple steps. If they are responding well after you get to 90%, then leave it there for a while and reduce the color a few percent each week or about 10% over the course of a month. Then you can try to increase the intensity a bit more. I have a hunch you can go to 100% intensity with your lighting height if you take it slow and reduce the color % some.

Thanks Scott,

Actually I have raise my intensity and color to 3 % last week before I posted here and I will maintain that till next week for another raise on intensity . I will just let color stay there until intensity have reached to the 90% but will watch the corals reaction along the coarse as your advises.

One thing I observed , some colors turn greenish colors , I don't know if this are their original colors or may be some algae ? I am still kindergarten to sps so still not able to distinguish well. But if these are their original colors they turning to , I may have to credited not to my light adjustment of last week but may be because I hook back my GFO yesterday and po4 this morning was 0.04 ppm from 0.18 two days ago and no3 today is 0.2 ppm from 0.5 ppm two days ago. Drastic drop indeed and I know it is not good.

Great thread!!

I'm running two a160's over my 65 gallon with the kessil controller and I'm really loving these lights. I did change over from the radion gen 3 pro which I had over this tank before I converted from softies to sps.

I am struggling with finding the right colour and intensity at the moment :headwally::headwally:

please forgive the iphone pics

What I like about kessil is their shimming

 

[SonnyJames]

Two a160's over a 3x18x18 is plenty strong

[SonnyJames]

could really use some help. just not sure what intensity to run these at

could really use some help. just not sure what intensity to run these at

I run my 2 a160we at 100% @ midday using the bluefish controller over my 57gal 36x18 footprint tank.

 

[minus9]

SonnyJames, I have two 160's over a 23x12x14 nano and I'm only hitting 70% intensity (mid day) during a 12hr cycle. The lights are 7" above the water and 10" apart from each other. I'm only ramping color to 30%. I've played around with the color quite a bit and I think if you're 50% and under, you'll be fine. You're really not changing the spectrum when you change the color %, just adding a little red when you increase and adding uv when you decrease. Also, the PUR % goes up with a lower color %. I think you'll be happy with color between 50% - 30%. As far as intensity, it all depends on what corals you have. Regardless, change color and intensity slowly and not at the same time. I have the spectral controller, so I make one adjustment a month, so no more than 5% during that time. If you're using an apex (or bluefish), you can change 1% - 2% a week and shouldn't have a problem. The key with Kessil's (and all LED's) is change slowly and be patient. Nothing good happens fast in this hobby.

 

[timger]

I know it's not 100% possible to say, but can someone come with a wild guess, on what intensity I should try and run my 2xA360WE on?

64G tank, around 18" high, and lights 11" over waterline.

Right now, LPS only, with 2 monti caps - and they are not looking to good after 1-2 weeks in my tank.

I run me Kessils at 25% intensity for 8-10hours a day. No ramping up and down

I run mine peak 50% with I think about 35% max whites. I do ramp and do run 12 hours. LPS are happy and SPS are growing pretty slow, but growing.

 

[pelphrey]

I currently have the 160 over a marineland 27 gallon cube and love it! I have plans to upgrade to a 150 gallon 60x24x24 tank in the future. I would love to stay with Kessil, my plan is to run one 360 on the left and one 360 on the right with the 160 in the middle. Do you all see any issues, will I need to run 3 360's on this size tank? Tank will be a mixed reef, no SPS initially but we know where this road goes!

 

[Scorpius]

I run mine peak 50% with I think about 35% max whites. I do ramp and do run 12 hours. LPS are happy and SPS are growing pretty slow, but growing.

I'm runing a max of 45% intensity and 40% color with my 360we's. I've noticed after I brown out and just about kill my sps they then recover, color up, and start growing decently. I don't know what the secret to light acclimating sps to these Kessil's as everything I've tried has failed.

LPS don't seem to care as much about light acclimation in my experience.

I know my problem is that I tend to underestimate the power of these lights and end up trying to increase intensity. I'm going to keep them at 50% for a while and resist the temptation to turn them up.

 

[minus9]

It's better to have sps brown out, then to bleach. They can survive much longer under low light, than too high light. They will color up again, but it's a very slow process, one that requires patience. Increase intensity no more then 5% - 6% a month. It doesn't sound like much, but these lights were tuned to the right spectrum, no matter what color setting you adjust. Again, it's better to go slow.

don't want to fry anything by going to 100% right away. I did replace a radion gen 3 pro for these two. wanted to give them a go and compare...so far very happy with them!!

I have the colour between 40% -50% and the intensity around 70%
ive replaced a radion pro gen3 over this tank and I must say I like the two kessils better. I had some shadowing with the one radion and didn't really want to put two over this tank. these two lights with the controller are a bargin in comparison!

HELLO ALL KESSIL AP700 USERS. PLEASE READ THIS IS IMPORTANT.
so tonight I come home late (around 1:30 am) and to make a long story short, my tanks lights are on full blast. Um what?!?!? Now I've experienced some other glitches that I can deal with but this is totally unacceptable. I have no clue how long my light has been doing this or how long it stays on for. I am never really awake at this time to know which is what worries me. I'm just curious if anyone has had an issue like this. I'm going to be calling Kessil tomorrow because this has to be solved immediatley imo. I am really not happy with this along with the other glitches and if this isn't fixed I will seriously be considering switching to something like radions.

This happened to me a couple of times and two things I did ensured that it never happened again.

Make sure you have the latest firmware.
When you are finished editing profiles, always hit the back button on the app to save progress and refresh on the opening screen to ensure your profile is green.

This never happened to me again, hope it works for you and I agree with you that the app sucks but calling Kessil isn't really going to help.

Unfortunately you're probably right. I remember one night I came down at midnight and the storm mode was running. But it wasn't the regular storm mode, like how it gets dark blue with the Lightning. It was bright white daylight with lightning! Which isn't even an option.
